1. Eukaryotic cells Animal and plant cells
Cellular Organelles
Eukaryotic cells
Animal and plant cells

2. The cell Most microscopic 3 main parts of the cell
Differ in size and shape
3 main parts of the cell
Plasma membrane
Cytoplasm
nucleus

3. Cell membrane Phospholipid bilayer
Regulates materials in and out of the cell
Contains proteins, carbs
and cholesterol
within the
membrane

4. Nuclear membrane and nuclear pores
Allow materials in and out of nucleus via the nuclear pores (small openings found within the membrane)

5. Nucleus Surrounded by nuclear envelope
Contains DNA – heredity information

6. Nucleolus Site where ribosomes are synthesized
Found within the nucleus

7. Ribosomes Involved in protein synthesis No membrane
Made of proteins and RNA
Individual or attached to Rough Endoplasmic Reticulum

8. DNA Genetic material Double helix
Provides instructions for proteins, regulate cellular activities, cellular reproduction

9. Cytoplasm Cell interior, internal living material
Consists of organelles and fluid
space from cell membrane and nucleus

10. cytoskeleton Provide support for the cell
Aids in the movement of organelles
2 components
Microfilaments
microtubules

11. Endoplasmic Reticulum
Intracellular highway
Rough
Covered with ribosomes
Synthesis of proteins
Smooth
No ribosomes
Synthesis of lipids, breakdown of toxins

12. Vesicle
Small membrane sac that transports materials in cell

13. Golgi Apparatus (bodies)
Processing, packaging and secretion
Stack of flattened sacs
Modifies proteins for export

14. Lysosomes Digestive, breaks down old organelles and substances
Secretes enzymes, high pH
Not in plants

15. Mitochondria Powerhouse of cell Supplies energy for the cell
Contains own DNA
Has a double membrane

16. Cell Wall Found only in plant cells Give support and protection
Contains cellulose

17. Chloroplasts
Light energy is converted to chemical energy ( photosynthesis)
Contains green pigment – chlorophyll
Found only in plant cells

18. Central Vacuole Large membrane bound space found in plant cell
Stores water, nutrients and wastes
When full, plant cells are rigid, making plant stand upright
Animal cells do have small vacuoles

19. Flagella and Cilia Cilia Flagella Short, hairlike Numerous Locomotion
Seen in respiratory system
Flagella
Long, whiplike
Less numerous
Used mostly for locomotion

20. Centrioles Aid in cell division of animal cell only
Composed on microtubules
